What does the differential pressure feedback exhaust sensor do?

This sensor varifies flow of the exhaust gases to the intake manifold. If flow is interupted the sensor will inform the onboard computer that the exhaust recirculation system has failed resulting in a check engine light to come on.

What is DPFE sensor?
Dpfe sensor is the delta (differential) pressure feedback egr (exhaust gas recirculation) it monitors the pressure on the egr valve to make sure it is working.
Why does exhaust gas recirculation pressure feedback sensor blow the hose off?
You have restriction in the exhaust somewhere and it's causing it to backflow.
What causes a P1405 Error Code on a Ford Ranger?
Differential Pressure Feedback Electronic Sensor circuit Upstream Hose
Where is the differential Pressure Feedback exhaust sensor located in a ford econoline e-150 v-6 van?
AnswerThe DPFE sensor is located next to the EGR vacuum regulator. The DPFE sensor is a rectangular box shaped sensor, held on by 2 nuts. It has two exhaust lines going to the EGR tube. This sensor is on 1996 and later models. joedi (edit: changed 1997 to 1996) joker_102877
What is a p1401 code on a 2000 Lincoln ls v6?

What does code P1401 mean on a 2002 ford ranger 4x4?
P1401 - Differential Pressure Feedback EGR sensor ( DPFE ) circuit high voltage detected
What is a delta pressure sensor?
It is a slang tern given to a Differential Pressure Sensor or Transducer.
99 Ford Explorer DPFE Sensor what does it do?
According to my Haynes repair manual, the Differential Pressure Feedback EGR sensor (DPFE) monitors upstream (before) and downstream (after) exhaust backpressure. By calculating the difference between the two pressures, the powertrain control module (PCM) determines exactly the EGR flow rate at all driving conditions.
How do you repair p0401?
The exhaust gas recirculation (EGR) system has insufficient flow. It could be caused by the differential pressure feedback EGR sensor being faulty, there t is a blockage in the EGR tube (most likely from carbon buildup), the EGR valve is bad, or the EGR valve may not be opening.
